MP3414AGJ Datasheet | Monolithic Power Systems

DESCRIPTION The MP3414A is a high-efficiency, synchronous current mode, step-up converter with output disconnect. The MP3414A can start up from an input voltage as low as 1.8V while providing inrush current limiting and output short-circuit protection (SCP). The integrated P-channel synchronous rectifier improves efficiency and eliminates the need for an external Schottky diode. The PMOS disconnects the output from the input when the MP3414A shuts down. The output disconnect feature allows the output to be discharged pletely, allowing the MP3414A to draw a supply current of under 1μA in shutdown mode. The 1MHz switching frequency allows small external ponents while the internal pensation and soft start minimize the external ponent count. These features produce a pact solution for a wide current load range. The MP3414A features an integrated power MOSFET that supports an output of up to 5.5V and a peak switching current above 3A. The MP3414A is available in a small 8-pin TSOT23 package.
